Royal Purple: HPS® High Performance Engine Oil with Synerlec®

Formulated for use in gasoline and diesel automotive, commercial fleet, and stationary industrial engine applications, HPS® Series engine oil from Royal Purple meets the demands of high performance and modified engines. Fortified with a high level of zinc/phosphorous anti-wear additive and proprietary Synerlec® additive (which prevents the oil from breaking down under the stresses of sustained heat and pressure), HPS® oil outperforms leading synthetic and conventional lubricants in gas and diesel engines.


  • Exceptionally high film strength for dramatic reductions in engine wear and heat
  • Improved sealing between the piston ring and cylinder wall maximizes horsepower and torque and optimizes fuel economy.
  • Exceptional oxidation stability extends oil life and allows for more miles driven between oil changes.
  • Advanced synthetic solvency reduces engine deposits and keeps engines clean.
  • Outstanding wear protection for valve train components, including performance roller lifter and high lift flat tappet camshafts and lifters.
  • Superior corrosion protection
